Cleaning solvent composition

Abstract

Provided is a cleaning solvent composition that comprises a cis-1-chloro-3,3,3-trifluoropropene solvent and an additive, wherein the additive contains at least one type of compound selected from the group consisting of nitroalkanes and epoxides.

1 . A cleaning solvent composition comprising a cis-1-chloro-3,3,3-trifluoropropene solvent and an additive, wherein the additive comprises at least one compound selected from the group consisting of nitroalkanes and epoxides. 
     
     
         2 . The cleaning solvent composition according to  claim 1 , wherein the additive comprises a nitroalkane. 
     
     
         3 . The cleaning solvent composition according to  claim 2 , wherein an amount of the nitroalkane is 0.1 wt % to 20 wt %, both inclusive. 
     
     
         4 . The cleaning solvent composition according to  claim 2 , wherein the nitroalkane comprises a nitroethane. 
     
     
         5 . The cleaning solvent composition according to  claim 1 , wherein the additive comprises an epoxide. 
     
     
         6 . The cleaning solvent composition according to  claim 5 , wherein an amount of the epoxide is 0.1 wt % to 20 wt %, both inclusive. 
     
     
         7 . The cleaning solvent composition according to  claim 5 , wherein the epoxide comprises a butylene oxide. 
     
     
         8 . The cleaning solvent composition according to  claim 1 , comprising:
 a nitroethane of 1 wt % to 2 wt %, both inclusive; and   a butylene oxide of 1 wt % to 2 wt %, both inclusive.   
     
     
         9 . The cleaning solvent composition according to  claim 1 , wherein the cis-1-chloro-3,3,3-trifluoropropene solvent further comprises a lower aliphatic alcohol. 
     
     
         10 . The cleaning solvent composition according to  claim 1 , wherein the cis-1-chloro-3,3,3-trifluoropropene solvent further comprises trans-1,2-dichloroethylene. 
     
     
         11 . The cleaning solvent composition according to  claim 1 , wherein the additive comprises a nitroalkane and an epoxide, and a total concentration of the nitroalkane and the epoxide in the cleaning solvent composition is 1 wt % to 20 wt %, both inclusive.
